C++ failure in 4.1.2 bootstrap on rs6000-ibm-aix4.3.0.0

Hi,

I was wondering whether anyone had come across a similar problem to
this.

I recently bootstrapped gcc 4.1.1 on powerpc-ibm-aix4.3.1.0 with
../gcc-4.1.2/configure   --with-gmp=/usr/local --with-mpfr=/usr/local
--disable-multilib --mandir=/usr/local/share/man
--infodir=/usr/local/share/info --enable-languages=c,c++,fortran,java

and everything appeared to build and install perfectly okay.

I then tried a bootstrap on rs6000-ibm-aix4.3.0.0 with:

/home/gcc-4.1.2/configure   --disable-nls --mandir=/usr/local/share/man
--infodir=/usr/local/share/info --with-mpfr=/usr/local
--with-gmp=/usr/local --enable-languages=c,c++

which failed at the final stage with:

make[6]: Leaving directory
`/archive/obj-gcc-constance/rs6000-ibm-aix4.3.0.0/pthread/ppc64/libiberty/testsuite'
make[5]: Leaving directory
`/archive/obj-gcc-constance/rs6000-ibm-aix4.3.0.0/pthread/ppc64/libiberty'
make[4]: Leaving directory

directory `/archive/obj-gcc-constance' make[1]: *** [all] Error 2
make[1]: Leaving directory `/archive/obj-gcc-constance' make: ***
[bootstrap] Error 2

As a double check I tried a bootstrap on a powerpc-ibm-aix4.3.2.0 with
/home/gcc-4.1.2/configure   --with-gmp=/usr/local --with-mpfr=/usr/local
--mandir=/usr/local/share/man --infodir=/usr/local/share/info
--enable-languages=c,c++,fortran,

and again ended up with the above error: *** No rule to make target
'all' when entering libstdc++-v3/

I've had a look through the ML archive, but it appears that most people
are either not using this platform much, or they haven't had any
problems!

I've historically always used --disable-multilib since 3.* to reduce
the bootstrap time and because I had bootstrap problems many years ago
with aix64 not being supported, but it does not appear to be related to
my current problem.

If all else fails I can just build the C and Fortran compilers and
ignore g++, but I'd quite like to work out what is going on.

Any suggestions?

Steve
